In the field of medium torque DC electric impact wrenches, various brands have launched new products to improve their performance, and DEWALT's original DCF894 is not so competitive. But this year's listing is the latestdewalt 20v max xrElectric impact wrenchdcf891After that, the situation has been reversed, so to speakBack in the first echelon. Power tools are eye-openingLet's take a look at these two products with you today.
dcf891Basic Performance Parameters:
Motor: Brushless.
Maximum output speed: 2200rpm
Maximum impact frequency: 2100ipm
Maximum Output Torque: 600 ft-lbs (812Nm) Tightening 800 ft-lbs (1084Nm) Release.
Before we look at the best products, let's review the old Dewalt mid-torque shock wrench DCF894, which has a tightening torque of 330 ft-lbs and a release torque of 600 ft-lbs.
The DCF891 has 600 ft-lbs of tightening torque and 800 ft-lbs of loosening torque. Compared to the old model,Increased tightening torque, release torque increasesThere has been a qualitative leap. How does that compare to the competition?The DCF891 is not top-of-the-line in terms of torque, although it is not the top of the game, but it is second to none in terms of torque.
The main engine switch is a variable speed switch. In addition, the speed control function DCF891 has been upgraded from the old 3-speed mechanical mode switchfile electronicsButton mode. In addition to low, medium and high gradesOne of the additional gears is Precision mode, which helps improve the user's control when tightening and unleashing.
In precision mode,When tightening,The tool will tighten at a positive rpm speed of 2000 rpm and will pause 05 seconds, and then continue the shock at a shock frequency of 3100 ipmReduced fasteningToo tight or damagedfastenersofRisksWhen neededWhen the nut is loosened, the tool will operate at normal speed and an impact frequency of 3100ipm. When it detects that the workpiece is starting to loosen, the tool will stop the impact and reduce the rotational speed toPreventThe nut suddenly dropped
dcf891Designed with LED lights,It can provide good illumination in poor lighting conditions, and it is designedSeparate high and low brightness adjustmentsoff
DCF891 sizeOverall length 7inches, there is room for further improvement(Miwoc's 2962 is 6 inches long). But the weight control is relatively goodNaked weight 38 pounds, mating on 5It has a working weight of 0 when it is 5ah battery3 pounds, of course the main unit is equipped with a belt buckle.
* Aspects,dcf891NakedmachineSelling priceUSDBundle versionThe selling price is:USDIn addition to the main unit, it is equipped with two 5.0ah battery, a charger and kit. There is also a DCF892 on the market at the same time, the only difference from DCF891 is the output head, the former is a square wave bead type, and the latter is a square circlip type.
On the whole,Power tools are eye-openingI think this 20V MAX XR medium torque impact wrench DCF891 is an upgraded product with a qualitative leapThe performance has reached the level of the first echelon in the industryAnd the precision mode is designedIt would be perfect if it could be made more compactNow, what do you think?
